Sport S to Willys

[Opus]

I think I know the answer, but just to be sure. If at some point I swap my Granite Crystal Sport S wheels (17 X 7.5, tires 245/75 R17) for a take-off set of black Willys wheels will I need to recalibrate the speedometer? I think the tires are slightly larger on the Willys, but I don't know if they are large enough to warrant the change.

No, the size difference isn’t enough to make any significant impact. The 255/75/17s on the Willys are 32.1”

At 60mph it's a 1.1mph difference.
